It's either Sensenbrenner or Mr.Mustard in the Library

Days after an internal probe by the Clerk of the Privy Council Office Kevin Lynch failed to determine the source of the Naftagate leak, James Travers at The Star reported that "Multiple sources say the Canadian note questioning the Democrat frontrunner's public promise to reopen NAFTA was leaked from the Prime Minister's Office" to Frank Sensenbrenner, a Republican who worked at the Canadian embassy in Washington.

Now Sensenbrenner's father, James, introduced the notorious U.S. Patriot Act as chair of the U.S. House Judiciary Committee, but just how did his son Frank appear in our midst?

"[Frank] Sensenbrenner was introduced to senior embassy officials by Gerry Chipeur, a Calgary-based lawyer who was once legal counsel to the Reform and Canadian Alliance parties, the antecedents of today's Conservative party.

Chipeur, a dual citizen who headed the Republicans Abroad Canada, also has deep ties to the evangelical community in both countries and prominent U.S. Republicans, including Kansas Senator Sam Brownback.

The entrée of Sensenbrenner into Canadian diplomatic circles was forged at the Republican National Convention in New York in 2004, where members of the Canadian embassy and Conservative officials such as Day, Chipeur, Alberta MP Jason Kenney and John Reynolds, co-chair of the Tory 2006 election campaign, all attended.

Sensenbrenner had cut his political teeth in Canada, attending private college in the Toronto area and attending early Reform party conventions where he first befriended those in then-leader Preston Manning's inner circle.

The push to get him on the payroll came particularly from Day, sources said, when he took over the Western Hemisphere Travel Initiative file, the name given to the Republican move to require all Canadians crossing the U.S. land border to carry passports or secure driver's licences."

I had no idea Day, Kenney, and Reynolds attended the U.S. Republican National Convention but I can't say I'm surprised. This old boys network is already so 'deeply integrated' they can't imagine what's taking the rest of Canada so long to catch up.

Frank Sensenbrenner has since denied having a role in the leak of the Canadian consular memo.
So due to that internal Privy Council Office probe which protects the Cons from having to answer any difficult questions, we're back to Mr. Mustard in the Library again.
